OSI Model Layer 1 - -Physical The Physical layer represents the physical medium that connects the computers together. OSI Model Layer 2 - -Data Link represents how computers logically connect to the network. Protocols at Layer 2 define how computers can share access to a common medium, such as a wired or wireless network. This includes protocols such as 802.3 Ethernet and 802.11 Wi-Fi. OSI Model Layer 3 - -Network allows computers on different networks to exchange data. OSI Model Layer 4...
